Savannah Guthrie's daughter Vale is only two years old - but she's already earning a reputation for being one of tennis pro Roger Federer's biggest, and most enthusiastic, fans.

In a video posted to Instagram by the 45-year-old Today show anchor - and then shared live on-air during an interview with the eight-time Wimbledon champion - the adorable toddler can be seen enthusiastically cheering on Swiss sports star Roger during his semi-final against Tomáš Berdych.

The cute clip shows Savannah and her daughter sitting on their couch watching the match, with Vale happily cheering, 'Roger! Roger! Roger!' at the camera, before her smiling mom joins in.

And Savannah couldn't wait for the opportunity to share the sweet video with Roger, broadcasting it live on air while speaking to the Wimbledon victor on Monday morning.

Speaking to the tennis pro via video, Savannah eagerly confessed to Roger - who powered his way to a nineteenth grand slam title on Sunday - that she is one of his biggest fans.

'I don't know if you've been informed Roger, but I may be your number one super fan, not just because you're an excellent tennis player, but because you seem to be such a sincere and excellent sport, and so many people have said that,' she said, prompting the Wimbledon champion to reply: 'Thank you so much for your support, I have been told and you're too kind.'

Clearly eager to cement her status as Roger's most dedicated fan, Savannah continued: 'Well I don't know if you know this, but my two-year-old daughter, a little girl named Vale, loves you very much, and we were watching your semi final and I wanted to show you a little piece of that tape I took.'

The cute clip shows Savannah and Vale cuddling together on a sofa in their New York home while watching Wimbledon on the TV, with a dungaree-clad Vale happily cheering, 'Roger! Roger! Roger!' at the camera.

'She is!' Savannah replied, adding: 'It is in her DNA, it is absolutely in her DNA.'

Bringing the interview to a close, Savannah added: 'I'm glad to see you holding the trophy, I wanted you to know I've been holding my tennis racket during this entire interview,' before holding it up to show the tennis gear to Roger.

After the interview was over, Savannnah's co-host Hoda Kotb mentioned that Roger had said the Today show anchor's name during the interview, with Savannah joking: 'I can die now, I wore red for Switzerland, I put Swiss cheese on my breakfast sandwich, it's a Roger day!'

Explaining her enthusiasm about speaking with the Wimbledon champ, Savannah added: 'He's such a great player, and he's a great sport, and that's truly why I admire him so much.

'And I think everyone on the tour loves him too so I'm in good company.'

Hoda admitted she was surprised to see Savannah in such a fluster over an interview, joking: 'I've never seen you quite like this, in all the years... this is special.'

Savannah replied: 'It's funny because [people] were saying I was a real dork around Duran Duran, and I said, "That's fine, I love Duran Duran," but that was 30 years ago I had the crush, this is a live crush right now, this is happening in current time.'

Earlier on during the interview, before sharing the clip of her daughter cheering Roger on, Savannah took a moment to congratulate the tennis pro on his eighth Wimbledon victory, before asking how it feels to have achieved such a feat.

Swoon! Hoda noted that she has never seen Savannah in such a fluster about an interview, prompting Savannah to admit that she has a 'live crush' on Roger

'Congratulations to you!' Savannah told the tennis pro during the interview, adding: 'I don't know if you've had any chance to sleep, if it's sunk in at all?

'I wonder what it feels like to have eight Wimbledon titles - is it like your children, you love them all equally, or is this one extra special?'

Roger replied that each of his victories 'feel different', explaining: 'I won the first one here 14 years ago, and it's so long ago now that I'm not even sure how it felt anymore, I just remember it was like a total dream come true.

'This time around, I came around as the favorite and things were different... I came in as the favorite and I'm a father of four... I don't know, it's just crazy.'

Posting a clip from the interview on her Instagram account following the broadcast, a delighted Savannah joked in the caption: 'Game, set, MATCH MADE IN INTERVIEW HEAVEN.'

The Today show anchor also took to the social media site to share an image of herself posing with her tennis racket ahead of the video chat, as well as a screen grab of a text sent to her by her colleague Dylan Dreyer, which simply read: 'Rog is on the show???? ARE YOU DYING???'
